very informative post. But what with we use coke after the whole cleaning process is completed? Will coke (being acidic) be able to restore more shine to the HS on top of the aluminium foil treatment earlier?

maybe should do this step without the last step of putting it to hotwater, detergent and aluminum foil..

the way I see it will be clean off the dirt first.. then follow by using coke.. maybe that will bring back the shine, but I wont advise to do it on nickel black. also side effect.. if this process that we keep doing it.. i affraid it might just bite off more metal, ended up with pot holes on the fins.. lol

Yes.. I did some digging and aluminum + coke + copper mix can produce small amount of voltage...
